# Matrix with Info Columns from different Table

Hi, how can i manage to have a column in a matrix that doesn't represent a value of the table the other columns are using?

For example, i have a matrix and this matrix has values of the UDT (@Table) and one column contains the projectcode. now i want one column in my matrix to show the project name of the OPRJ. how can i manage that, so that the value of this column in the matrix changes when i change the value of the other column with the project code?

best regards

Philipp
